A Novel Protection Method for Single Line-to-Ground Faults in Ungrounded Low-Inertia Microgrids [PDF]
Energies, 2016 This paper proposes a novel protection method for single line-to-ground (SLG) faults in ungrounded low-inertia microgrids. The proposed method includes microgrid interface protection and unit protection. The microgrid interface protection is based on the

Single-Phase Fault Line Selection in Distribution Network Based on Signal Injection Method
IEEE Access, 2021 The distribution network with small current grounding mode can ensure high power supply reliability, but it is difficult to locate single-phase grounding fault line. Most of the faults in distribution network are single-phase to ground fault.
